In search of electric power reliability in forested terrain with covered conductors the ECG experience

A failure condition known as burndown and surface tracking of covered conductor insulating material appears to be restricting the widespread use of covered conductors in Ghana. The paper identifies specific problems militating against the use of covered conductors and reviews international experience on the subject with the aim of developing a performance system specification for covered conductor use in Ghana. The paper also discusses advances in protection methods for detecting downed covered conductors and recommends effective protection scheme that must go with the adoption of covered conductors.
